Formula:
                                            I    W
                                              qN2
                                     I qN1     W qN2 qN2


                Where:

                I qN1: Production index of the VSIC 1-digit sectors.

                I qN2: Production index of the VSIC 2-digit division.

                W qN2: Weight of the VSIC 2-digit divisions. Weight of the VSIC 2-
                       digit divisions is the value added at current price of the base
                       year 2015.
                Step 5: Calculating production index of the whole industry

                The production index of the whole industry is the weighted average
          index of VSIC 1-digit sectors representing in the whole industry.

                Fomula:

                                            I    W
                                     I        W qN1 qN1
                                              qN1
                                      Q


                Where:
                I Q: Production index of the whole industry.

                I qN1: Production index of the VSIC 1-digit sectors.

                W qN1: Weight of the VSIC 1-digit sectors. Weight of VSIC 1-digit
                       sectors is the value added at current price in 2015.

                Industrial  product  is  an  indicator  reflecting  the  direct  results
          generated  by  industrial  production  in  a  given  period  including  industrial
          physical products and services.

                Industrial  physical  products  are  industrial  products  generated  by
          using working instruments acting upon object to turn the original mode of
          materials  into  new  products  with  new  utilization  value  or  products

          explored  from  mines.  Industrial  physical  products  include:  (1)  Finished
